Run a private construction payment chain where each milestone is escrowed and released only after an independent certifier signs off. Developers, main contractors, and subcontractors share one neutral record, so a completed milestone triggers payment instead of a standoff.
Turn a contested milestone paper trail into escrowed, certifier-gated settlements.
01.
The developer funds each milestone into an Escrow and Conditional Settlement vault up front, so subcontractors can see the money is committed before they begin the work.
02.
A neutral project certifier signs the completion of each tranche on-chain. No party can release or withhold funds unilaterally, since the signature is the release condition.
03.
Once the attestation lands, the contract pays the subcontractor automatically within the same block, collapsing a months-long dispute window into a single settlement.
04.
Every purchase order, variation, and back-charge is recorded against the milestone, so the paid amount always reconciles to the agreed scope.
05.
Site progress evidence, inspection photos, and completion reports are anchored by digest, giving the certifier tamper-evident proof to sign against.
06.
Payments cascade down the contracting tree, so a main contractor cannot sit on funds owed to a subcontractor after its own tranche has cleared.
Follow one construction milestone from funding through certifier sign-off to subcontractor payment.

Cerulea splits milestone settlement into modular contracts. Each layer funds, evidences, certifies, and releases a tranche without letting any single party control the flow of money.
Certifier-gated milestone settlement is a horizontal capability. Here is how different construction actors put the escrowed payment chain to work.
Fund milestones into escrow and pay only against independent sign-off, protecting cash flow while giving trades confidence that committed money is ready to release on completion.
Key Asset Types
Manage a full subcontractor tree on one ledger, cascading payments down the chain automatically once each tranche certifies and eliminating manual reconciliation at close-out.
Key Asset Types
See funds committed before mobilizing and get paid within 24 hours of certifier sign-off, removing the months-long wait that disputed milestones normally impose.
Key Asset Types
Whether you are bridging a developer's ERP and project controls or capturing site progress from a foreman's phone, Cerulea routes both into one escrowed settlement record.
For developers and tier-one contractors on ERP and project management suites. Milestone schedules and cost lines translate into escrow funding and release calls through the API gateway.

Escrowed Payment Record
Building an escrowed milestone system with certifier gating, cascading subcontractor flows, and procurement reconciliation from scratch requires specialised engineers and long integration cycles. Calculate your exact deployment speed using Cerulea.

The legacy timeline reflects enterprise construction-tech integration benchmarks. Wiring escrow custody, certifier gating, and cascading subcontractor payments into a developer's project controls for an average program takes a baseline of 8 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your milestone and release rules into pre-audited WebAssembly binaries and provisions the escrow and attestation layers instantly.
